A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest prices is intricate by th
